SolidJS Development Service

Production SolidJS apps and SolidStart sites built by engineers who understand signals and fine-grained reactivity. Subscription pricing.

When Signals Beat Virtual DOM

SolidJS looks like React but is not React. The JSX is the same. The component model is similar. But the reactivity is fundamentally different: there is no virtual DOM, no re-render of the entire component on state change, no `useEffect` hell. State is a signal, derived values are memos, and the framework updates the exact DOM nodes that depend on what changed.

This makes SolidJS one of the fastest frameworks available. Real-world apps see better TTI, smaller bundle sizes, and lower memory footprints than the React equivalent. The framework itself is tiny (under 10KB). For data-heavy dashboards, charts, real-time UIs, and anything performance-sensitive, Solid is genuinely better than React.

The mental shift trips up React developers. In React, you write code that runs on every render and try to memoise the expensive parts. In Solid, you write code that runs once and let signals propagate changes. Closures over signals capture the signal, not its value. `setStore` for nested state requires a different syntax than `setState`. Engineers who skip the mental adjustment write Solid code that compiles but does not benefit from fine-grained reactivity.

SolidStart is the meta-framework: file-based routing, server functions, deployment adapters. It is younger than Next.js or Nuxt and the ecosystem is smaller, but it works and the deployment story is solid (Cloudflare, Vercel, Netlify, Node). UI primitives via Kobalte or Ark-UI fill the gap that Radix fills for React.

AsyncForge has senior Solid engineers shipping production apps. Submit a component, a SolidStart route, a migration from React to Solid, or a full app build. Light 4 days, Standard 48 hours, Pro 1 day.

What You Get

Signals over hooks

State management via `createSignal`, `createMemo`, `createEffect`. No dependency arrays, no stale closures, no `useCallback` ceremony.

SolidStart apps

Full-stack apps with file-based routing, server functions, and deployment adapters. SSR, SSG, or SPA per route.

Stores for nested state

`createStore` for nested objects and arrays with proxy-based reactivity. Granular updates to deeply nested fields without re-rendering the whole tree.

Resources for async data

`createResource` with built-in suspense integration, refetching, and error handling. The Solid equivalent of TanStack Query, baked into the framework.

UI primitives via Kobalte

Accessible primitives (dialogs, popovers, dropdowns, tabs) styled with Tailwind. The Radix-equivalent for Solid.

React-to-Solid migrations

Component-by-component migration of React apps to Solid for performance-critical pages.
